code.I don't quite agree with this approach:1. This makes unit testing difficult (because the module internally relies on external configuration);2. On the other hand, the configuration file as the interface of the user control program, the user should be free to specify the path of the file;3. The reusability of the program components is too poor, because this code through all modules hard-coded way, so that most of the modules rely on conf.py this file;So, I think the use of configuration, th

During the catalog backup recovery process, the import job terminates abnormally under certain conditions. At this point, catalog will be in a damaged state: The original catalog can not continue to use, import job can not continue. This article mainly introduces an example of such a scene, then restores and proposes how to avoid this anomaly.
